Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 23, 2024The c.239T>C (p.I80T) alteration is located in exon 3 (coding exon 3) of the TM6SF1 gene. This alteration results from a T to C substitution at nucleotide position 239, causing the isoleucine (I) at amino acid position 80 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
